What are GeneSTAR MVPs Now GeneSTAR® from Pfizer Animal Genetics provides a new 56 DNA-marker panel that delivers more genetic information on core traits with greater reliability. ® GeneSTAR MVPs—or Molecular Value Predictions—measure the molecular breeding values for the traits of feed efficiency, marbling and tenderness. This new panel, authenticated through a third-party validation process, will enhance genetic improvement by providing more reliable information to enable greater selection opportunities. GeneSTAR MVPs incorporate the 11 DNA markers included in the previous GeneSTAR test along with information from an additional 45 DNA markers to form the new 56 DNA-marker panel. MVPs are reported in units of the trait as a prediction of the animal’s genetic value.

Reading the MVP data, the animal in the example below has a GeneSTAR MVP feed efficiency value of -0.73 lbs. and a % rank value of 26 percent. This means that the MVP value for this animal ranks in the top 26 percent of animals within the same breed. As a full-service genomics provider, Pfizer Animal Genetics offers a team of professionals to help customers achieve maximum value from the application of test results in production-marketing systems. This includes helping you understand test information and apply results to your own management and marketing programs. *The closer the MVP value is to the highlighted Minimum or Maximum in each row, the more favorable the result. **The reliability value is expressed as a percentage of the maximum accuracy attainable.
